Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646468, here are decompositions:

11 + 8646457 = 8646468
67 + 8646401 = 8646468
79 + 8646389 = 8646468
107 + 8646361 = 8646468
139 + 8646329 = 8646468
151 + 8646317 = 8646468
191 + 8646277 = 8646468
199 + 8646269 = 8646468

Showing the first eight; more decompositions exist.
